3 Babcock Valves Heritage In 1967, Babcock Wilcox Española -present in the Spanish market since implemented its diversification policy by setting up a valve manufacturing division, which soon became one of the leading players on the international market, thanks to its engineering efforts, developing new designs to improve product reliability in the power generation sector (nuclear and conventional), petrochemical industry, oil & gas sectors and water works. Babcock Valves has the expertise, the know-how and the industrial experience of a company with almost half a century of history behind it, and a legacy of over valves installed all around the world. At Babcock Valves our commitment to our customers is underlined by a combination of tradition and continuous innovation. Our name is recognised around the world as a benchmark for reliability and service excellence, with hundreds of customers expressing their satisfaction with our supplies, taking advantage of the right performances of our valves for years.

5 Know-how + Expertise = Babcock Valves ENGINEERED TO THE LIMIT At Babcock Valves we use the latest software tools to develop and improve our own designs, to ensure the products we supply always comply and exceed the latest standards and international regulations. Our engineering team can guarantee the quickest possible response to meet our customers requirements, anywhere in the world. TECHNOLOGICAL BACKGROUND Babcock has developed its own solid, high value-added, valve-manufacturing technology over a period of 40 years. Initial agreements with technology leaders were followed by the development of our own in-house engineering facilities, in compliance with the main regulations and standards, and by studying customer specifications and applying advanced design tools.

7 Research, Development and Innovation R+D+I TO THE LIMIT Babcock Valves has its own Research + Development + innovation Department (R+D+i) that works each and every day towards the same goal: how to improve our valves. In doing so we use the latest software tools and technology to improve our own designs and develop new products, providing our customers with the best technical solutions and obtaining significant advantages over the competitors. Babcock Valves designs are based on advanced computer simulations, which minimize the possibility of design shortcomings and deficiencies affecting our valves, thereby ensuring our products always meet the latest applicable standards and customer requirements. We design our own range of products with special emphasis on safety, low maintenance, long service life and the highest quality, optimizing the entire production process to offer competitive prices. Our R+D+i team guarantees the quickest response to meet our customer requirements with personalized service.

9 Manufacturing Process Plan (MPP) The manufacturing process at Babcock Valves is carefully controlled by our Q.A. staff, from receipt of purchase order to dispatch of the goods. Each stage of the production process is conducted at own facilities or in cooperation with recognised and approved suppliers. Casting quality, particularly in the case of alloys, special alloys and exotic materials, is guaranteed by working with foundries equipped with the most advanced production systems plus the Non-Destructive Tests required for each piece. Precision machining, including processes such as valve seat and disc lapping, welding or surface hardfacing, are fully controlled by our experienced staff, ensuring that all valve components reach the assembly stage in perfect working condition. All valves manufactured by Babcock Valves are fully tested at our wide range of testing benches. Where required, any painting system can be applied at our facilities. Our goal is to produce zero defects and long-life valves.

10

11 After Sales Service With more than valves installed all around the world, our commitment is to provide our customers the very best after sales service. Therefore, we are ready at Babcock Valves to supply a full range of guaranteed spare parts for our entire product range, covering all of our products, both old and new designs. Our specialized technical staff is available for on-site maintenance and/or technical support such us plant s shutdown maintenance. In addition to this, we provide analysis & trouble-shooting solutions to establish the causes of valve failures, valve accessories, related technical equipment, customized maintenance proposals, valve type selection, design alternatives advice, assessment of pipeline and fluid influence over valves and technical advice to improve valve operation. Finally, training on Product Use & Maintenance for professionals is also into our abilities.

12

13 Quality & Certifications To guarantee high levels of quality for all of our products, our Quality Assurance Department implements a rigorous control and testing system throughout the manufacturing process. Moreover, Babcock Valves keeps an operational quality control and assurance manual that enables us to maintain optimum quality levels. All of our products are tested during the design phase and after assembly, prior to shipment. Testing includes cryogenic tests, hot cycle tests, multi-axis vibration tests, aging tests, flow and pressure tests, seismic resistance tests, valve hammer-impact tests, actuator tests and others. Our valves are designed, manufactured and inspected, in accordance with the most relevant international standards, such as: API ANSI (American Petroleum Institute) (American National Standards Institute) AWWA (American Water Works Association) DIN (Deutsche Norm) JIS (Japanese Industrial Standards) BS (British Standards) AFNOR (Association Française de Normalisation) MSS (Manufacturers Standardization Society) ISO (International Standards Organization) UNE (Spanish Standard) EAC Eurasian Conformity

36 different valves. A single philosophy. Each day, an army of Babcock valves works silently and tirelessly for many of the industries that really move our world. Babcock Valves S.A. P.E. Abra Industrial, Parcela Ortuella-Bizkaia (Spain) Phone: (+34) Fax (+34) info@babcockvalves.com nearest airport: Bilbao 25 Km. nearest seaport: Bilbao 6 Km. Reliability. One world. A meaningful philosophy. We have had this concept in mind since our inception in 1967, as the valve division of Babcock Wilcox Española. We have always understood that the world s leading industries cannot stop operating due to a failed element in their production systems. That s why we design our valves to last longer, and to be problem-free: so you can forget about them. Because we can imagine the consequences should it be necessary to take a water plant offline, or a gas pipe, due to a technical fault. Or the consequences of any downtime for the power generation industry. This is why we believe we are still trusted by so many of our initial customers, and the reason why we have over valves installed in leading companies around the world. We are mainly present in the following sectors: Power Generation (Nuclear and Conventional), Petrochemical Industry, Oil & Gas, Chemical, Fertilizer, at water treatment plants, etc. Our constant focus on quality is the foundation of our work. Our position as leaders in our sector is backed up by our Design Department that, together with the R+D+I centre, provides solutions to all of our customers requirements. Our highly qualified workforce constantly strives for improvement and maintains a service ethos in meeting our customers needs. This brochure contains the most representative items in our range of valves. However, modern techniques and customer requirements continuously impose material and design challenges, and we can therefore work to any specifications not covered in this catalogue. Our valves are designed, manufactured and inspected, in accordance with the most relevant international standards, such as: API (American Petroleum Institute) ANSI (American National Standards Institute) AWWA (American Water Works Association) DIN (Deutsche Norm) JIS (Japanese Industrial Standards) BS (British Standards) AFNOR (Association Française de Normalisation) MSS (Manufacturers Standardization Society) ISO (International Standards Organization) UNE (Una Normativa Española)
